換行函數(shù)在ShangchuanNews.jsp 代碼如下

<%@page import="java.io.PrintWriter"%>
<%@page import="java.net.URLDecoder"%>
<%@ page language="java" contentType="text/html; charset=utf-8" 
 pageEncoding="utf-8" %> 
<%@ page import="java.sql.*" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; utf-8"> 
<title>上傳新聞</title> 
</head> 
<body> 
<%! // 字符處理函數(shù) 換行符變成<br>
public String turn(String str) { 
 while (str.indexOf("\n") != -1) { 
  str = str.substring(0, str.indexOf("\n")) + "<br>" 
    + str.substring(str.indexOf("\n") + 1); 
 } 
 while (str.indexOf(" ") != -1) { 
  str = str.substring(0, str.indexOf(" ")) + " " 
    + str.substring(str.indexOf(" ") + 1); 
 } 
 return str; 
} 
%>
<% 
try {
 request.setCharacterEncoding("utf-8");
 String title = request.getParameter("title");
 String author = request.getParameter("author");
 String article = request.getParameter("articleName");
 String articlebr = turn(article);
 String date = request.getParameter("date");
 String driverClass="com.mysql.jdbc.Driver";
 String url = "jdbc:mysql://****.****/****?characterEncoding=utf8";//存到數(shù)據(jù)庫(kù)不會(huì)亂碼
